The electric ventilating butterfly valve can electrically adjust the opening and closing degree of the ventilating butterfly valve. (0-180 degree adjustment) The design is novel and reasonable, the structure is special, the weight is light inside, and the opening and closing is rapid. The operating torque is small, the operation is convenient, labor-saving and dexterous. Use suitable materials to meet the requirements of low, medium and high medium temperatures and corrosive mediums. The electric ventilating butterfly valve is designed and manufactured by adopting a new type of structure welded between the center line type disc plate and the short structure steel plate, which avoids the influence of high temperature expansion and is easy to operate. There are no connecting rods, bolts, etc., so it works reliably and has a long service life. It can be installed in multiple positions and is not affected by the flow direction of the medium.
It is used in dusty cold air or hot air gas pipelines of ventilation and environmental protection projects in chemical, building materials, power stations, glass and other industries, as a pipeline control device for regulating or cutting off the gas medium. This type of valve should generally be installed horizontally in the pipeline.
